javaMD5值加密代码！

import java.io.UnsupportedEncodingException;import java.security.MessageDigest;import java.security.NoSuchAlgorithmException;import sun.misc.BASE64Encoder;public class MD5 {    /**     * @param args     * @category MD5     */    MessageDigest m;    BASE64Encoder b;    String n;    publicpublic String complie(String s){try {s = s.trim();m = MessageDigest.getInstance("MD5");b = new BASE64Encoder();} catch (NoSuchAlgorithmException e) {e.printStackTrace();}try {n = b.encode(m.digest(s.getBytes("UTF-8")));} catch (UnsupportedEncodingException e) {e.printStackTrace();}return n;}}

做代码的时候经常需要对密码加密！
